Adviser: Beaton, John. Thesis (Ph.D.)--University of California, Davis, 2004. This dissertation examines spatio-temporal patterns of obsidian use on the Volcanic Tableland and their implications for long-term change in lithic technology and regional settlement ranges in the western Great Basin. The core of the study is a massive set of obsidian source and hydration data, fostered by the use of existing artifact collections and new materials recovered through survey and excavation. Shifts in flaked stone technology occur with the introduction of the bow-and-arrow. At the Newberry/Haiwee transition 1400 B.P.), the switch from Elko dart points to Rosegate arrow points was accompanied by changes in the roles and forms of bifaces, cores, and flake tools. Also, projectile points are shown to be useful time markers in the Great Basin, using hydration data and point types as proxy measures. Throughout its prehistory, the Tableland was occupied by groups entering mainly from the north and northeast. Early and middle Holocene occupations ca. 8500--4000 B.P.) centered on Fish Slough. Visitors came from extreme distances north and south, stopping only briefly. Between 4000--1400 B.P., occupations shifted to the plateau, people hailing from shorter distances to the north/northeast. Habitations were extended or repeated enough to produce middens and focused on dryland plants and animals. More recent occupations ca. 1400--200 B.P.) targeted plateau sites, and reused sites at Fish Slough, emphasizing the bulk procurement and processing of dryland seeds. Ricegrass was gathered while green and "flash-burned" to remove chaff, the seeds ground on bedrock with two-handed manos. Visitors had restricted northern territories, making settlement moves between western Nevada, the Mono Basin, and Long Valley. The presence of Owens Valley groups was limited, the terminal prehistoric pattern 200 B.P.--Contact) showing near exclusive use by northern populations. Major sites were again reoccupied and used to process seed plants in bulk. Late Holocene settlement systems including the Tableland saw the kind of spatial circumscription commonly ascribed to the Owens Valley settlement regime. This suggests other populations in eastern California/western Nevada experienced conditions of growth and competition, the effects of which led to subsistence intensification across the Inyo-Mono region.
